Every dollar you spend on Google Ads is filtered through a number most advertisers ignore or misunderstand: Quality Score. It is a 1-to-10 rating Google assigns to each keyword, and it directly determines how much you pay per click and where your ads appear. A keyword with Quality Score 8 can cost half as much as the same keyword at 4 — same search term, same audience, dramatically different economics.

This guide breaks down what Quality Score is, how to check it, and how to improve each component step by step. Actionable tactics you can implement this week.

What Is Google Ads Quality Score?

Quality Score is Google’s diagnostic rating of keyword, ad, and landing page quality. Displayed on a 1 (worst) to 10 (best) scale at the keyword level, it is calculated from three components, each rated “Below Average,” “Average,” or “Above Average”:

1. Expected Click-Through Rate (Expected CTR)

Google’s prediction of how likely your ad is to be clicked when shown for that keyword, based on historical performance compared to other advertisers. It normalises for position effects — a low position does not automatically penalise you.

2. Ad Relevance

How closely your ad copy matches the intent behind the keyword. If someone searches “office cleaning services Singapore” and your headline reads “Professional Office Cleaning in Singapore,” ad relevance is strong. A generic facilities management message would score poorly.

3. Landing Page Experience

Google evaluates the page users land on after clicking — content relevance, load speed, mobile-friendliness, navigation clarity, and trustworthiness. A fast, relevant page with clear calls to action scores well. A slow, generic homepage does not.

Quality Score is recalculated regularly as Google accumulates data. It is not static — your actions directly influence it over time.

Why Quality Score Matters (SGD Worked Example)

Quality Score feeds directly into Ad Rank, which determines ad position and actual CPC:

Ad Rank = Max CPC Bid × Quality Score

Higher Ad Rank means better position and lower cost. Here is a worked example for a Singapore business bidding on “corporate accountant Singapore”:

Metric Advertiser A (QS 4) Advertiser B (QS 8)
Quality Score 4 8
Max CPC bid SGD 6.00 SGD 6.00
Ad Rank 24 48
Estimated actual CPC SGD 5.80 SGD 3.10
Monthly clicks (same budget SGD 3,000) 517 clicks 968 clicks
Ad position 3rd or 4th 1st or 2nd

Same keyword, same bid, same budget. Advertiser B gets 87% more clicks, pays 47% less per click, and appears higher. Over a year, that compounds to tens of thousands of dollars in additional traffic — or equivalent savings. This is why Quality Score optimisation is one of the highest-leverage activities in any Google Ads management engagement. It requires better execution, not more budget.

How to Check Your Quality Score

Quality Score is not shown by default. Here is how to surface it:

Step 1: Navigate to Keywords

In your Google Ads account, go to Campaigns → Ad groups → Search keywords.

Step 2: Add Quality Score Columns

Click the Columns icon above your keyword table, then Modify columns. Search for “Quality Score” and add these four columns: Quality Score (the 1–10 rating), Expected CTR, Ad relevance, and Landing page experience (each rated below average, average, or above average). Optionally add the historical versions to track changes over time.

Step 3: Apply and Analyse

Click Apply. Sort by Quality Score ascending to surface your weakest keywords first. Filter for keywords with significant spend but scores below 6 — these represent your largest cost-saving opportunities.

Improving Expected CTR

Expected CTR reflects how compelling your ad is relative to competitors. Here is how to improve it.

Write Headlines That Match Search Intent

Your headline is the single biggest driver of CTR. Include the target keyword in at least one headline, but go beyond insertion — address the searcher’s actual intent. Someone searching “cheap office furniture Singapore” wants price signals. Someone searching “ergonomic office chair review” wants expertise.

Use Responsive Search Ads (RSAs) Effectively

RSAs allow up to 15 headlines and 4 descriptions. Google tests combinations and serves the best performers. Key practices:

  • Provide genuinely distinct headlines — not 15 variations of the same phrase
  • Pin your strongest keyword-inclusive headline to Position 1
  • Include headlines with numbers or differentiators (“Trusted by 500+ SG Businesses,” “Free Consultation Today”)
  • Write descriptions that reinforce the headline promise with a clear call to action

Leverage Ad Extensions (Assets)

Extensions increase your ad’s visual footprint, directly improving CTR. At minimum, implement:

  • Sitelinks — link to pricing, case studies, contact pages
  • Callouts — highlight benefits (“No Lock-In Contracts,” “Same-Day Response”)
  • Structured snippets — list service categories or product types
  • Call extensions — essential for Singapore businesses where phone enquiries convert well
  • Location extensions — show your physical presence if applicable

Extensions do not guarantee display, but Google factors their expected impact into Ad Rank. Filling them out comprehensively gives you an edge. Review RSA asset performance reports regularly and replace headlines rated “Low” with new alternatives — CTR improvement is iterative.

Improving Ad Relevance

Ad relevance measures how well your ad copy aligns with its triggering keywords. The fix is structural as much as creative.

Tighten Your Ad Group Structure

The most common cause of poor ad relevance is bloated ad groups — too many loosely related keywords served by a single generic ad. When “payroll services Singapore,” “HR outsourcing,” and “employee benefits management” share one ad group, no ad can be relevant to all three. Group keywords by tight thematic clusters so one set of ads speaks to all keywords naturally.

SKAGs vs Themed Ad Groups

SKAGs (Single Keyword Ad Groups) were the gold standard — one keyword per ad group, maximum relevance. They still work but create management overhead that scales poorly. The modern best practice is tightly themed ad groups with three to eight closely related keywords:

  • Ad group: “Office Cleaning Singapore” — keywords: office cleaning singapore, office cleaning service singapore, commercial office cleaning singapore, professional office cleaning singapore
  • Ad group: “Carpet Cleaning Commercial” — keywords: commercial carpet cleaning singapore, office carpet cleaning, carpet cleaning service office

Each group generates meaningful data while staying tight enough for relevant ad copy. This is the structure we use across our SEM campaigns for Singapore clients.

Mirror Keywords in Ad Copy

Write ad copy that directly reflects the keywords in each group. The target keyword should appear in at least one headline (ideally pinned to Position 1), at least one description, and the display URL path where applicable. This is not keyword stuffing — it is ensuring your ad clearly addresses the specific term and intent.

Use Keyword Insertion Sparingly

Dynamic keyword insertion (DKI) helps with relevance at scale but produces awkward copy with long-tail or grammatically odd queries. Use it as a supplement, not a substitute for well-written headlines.

Improving Landing Page Experience

Landing page experience is the component most advertisers neglect because it requires web development work, not just campaign adjustments. That neglect is an opportunity — improving your landing pages lifts Quality Score and conversion rates simultaneously.

Page Speed

Google explicitly factors load time into landing page experience. Aim for LCP under 2.5 seconds, FID under 100 milliseconds, and CLS under 0.1. Test with Google PageSpeed Insights. Common fixes: compress images, implement lazy loading, minimise render-blocking JavaScript, and use a CDN with Singapore edge nodes.

Mobile Experience

Over 70% of Google searches in Singapore happen on mobile. Your landing page must be fully responsive with tap-friendly buttons, readable text without zooming, and forms that are easy to complete on a phone. If users must pinch and scroll to find your enquiry form, both Quality Score and conversion rate suffer.

Content Relevance and CTAs

The landing page must deliver on the ad’s promise. If your ad says “Get a Free SEO Audit,” the landing page should feature that offer prominently — not a generic services page where it is buried three scrolls down. This often means creating dedicated landing pages for high-spend ad groups rather than sending all traffic to your homepage. The investment in conversion rate optimisation pays dividends across Quality Score and business results alike.

Every page needs an obvious, above-the-fold CTA — an enquiry form, click-to-call button, or WhatsApp link. Do not make users guess what to do next.

Trust Signals

Google evaluates page trustworthiness. Include client logos or testimonials, industry certifications, clear business address and contact details, privacy policy links, and HTTPS (non-negotiable).

Common Quality Score Myths Debunked

Myth 1: Pausing Low-QS Keywords Improves Account-Level Quality Score

Reality: There is no “account-level Quality Score” used in auction calculations. Quality Score is keyword-level. Pausing a QS 3 keyword does not boost your other keywords’ scores.

Myth 2: Quality Score Updates in Real Time

Reality: The visible score is a periodic snapshot. Google’s actual auction-time quality assessment runs in real time and considers additional factors (device, location, time of day) the displayed score does not reflect. Treat the visible number as a directional guide.

Myth 3: You Need a Quality Score of 10 on Every Keyword

Reality: Seven or above is strong for most commercial keywords. Branded terms naturally score 8–10. Competitive generic keywords may sit at 6–7 even with excellent optimisation. Chase improvement, not perfection.

Myth 4: Higher Bids Improve Quality Score

Reality: Bid amount has no direct effect on Quality Score. Calculations normalise for position effects. You cannot buy your way to a higher score — you earn it through relevance and performance.

Myth 5: Quality Score Does Not Matter for Smart Bidding

Reality: Automated strategies (Target CPA, Maximise Conversions, etc.) still use auction-time quality assessments. Higher-quality ads and pages result in lower costs even under Smart Bidding.

Quality Score Benchmarks

Use this table to assess where your keywords stand and where to focus your optimisation efforts:

Quality Score Rating What It Means Action Required
1–3 Poor Severe mismatch between keyword, ad, and landing page. You are significantly overpaying for every click. Urgent restructuring needed. Rewrite ads, review ad groups, and build dedicated landing pages. Pause if the keyword is not core.
4–5 Below Average Noticeable relevance gaps. CPCs are 25–50% higher than they should be. Identify which component is dragging the score down and address it specifically.
6 Average Acceptable but not competitive. You are paying roughly the baseline CPC for your market. Targeted improvements — often one component is holding the score back. A focused fix can push this to 7–8.
7–8 Good Strong performance. You are paying below-market CPCs and earning favourable ad positions. Maintain and monitor. Continue testing ad copy and landing page improvements incrementally.
9–10 Excellent Exceptional relevance and performance. Typical for branded keywords and highly optimised campaigns. Protect what is working. Focus optimisation time on lower-scoring keywords elsewhere in the account.

For most Singapore businesses, a spend-weighted average Quality Score of 7 or above indicates a well-optimised campaign. Below 5 signals significant waste in your ad spend.

How long does it take for Quality Score to improve after making changes?

For keywords with moderate to high traffic, expect score changes within one to two weeks. Low-volume keywords can take several weeks because Google has less data to recalculate with. The auction-time quality assessment adjusts faster than the visible score in your account.

Does Quality Score affect Display and Shopping campaigns?

The visible 1–10 metric is specific to Search campaigns. However, Google uses quality-based assessments across all campaign types — Display factors in landing page experience and relevance; Shopping uses product data quality and landing page experience. The principles of relevance and user experience apply everywhere.

Should I delete keywords with low Quality Scores and re-add them to reset the score?

No. Google ties Quality Score history to the keyword itself, not to the entry in your account. Deleting and re-adding does not reset anything. The only path is genuine improvement to CTR, ad relevance, and landing page experience.

Can I improve Quality Score without changing my landing page?

If landing page experience is already “Average” or “Above Average,” ad copy and structural improvements can meaningfully lift your score. If it is “Below Average,” you will hit a ceiling. For Singapore businesses with older websites, a landing page redesign often delivers the largest single improvement.

What Quality Score should I target for my Singapore Google Ads campaigns?

Aim for 7 or above on core commercial keywords. Branded terms should sit at 8–10. Broad or informational keywords may settle at 5–6, which is acceptable if they convert at reasonable cost. The key metric is your spend-weighted average — if you are spending the most on keywords with the lowest scores, prioritise those first.

Quality Score optimisation is not a one-time project — it is an ongoing discipline of aligning keywords, ads, and landing pages with what users search for and expect to find. The reward is concrete: lower costs, better positions, and more conversions from the same budget.
